SN74LV1T125DCKR single bus buffer gate 3-state output SC-70-5
The SN74LV1T125DCKR, a single bus buffer gate with 3-state output from TI, is housed in a compact 5-pin SC-70 surface-mount package, engineered to provide a robust, low-voltage interface for digital signal buffering and bus driving in space-constrained portable and battery-powered applications. This buffer operates from a wide 1.65V to 5.5V supply voltage range, supporting mixed-voltage interfacing between various logic families, and features a 3-state output controlled by an active-low output enable (OE) input that places the output in a high-impedance state when OE is high, enabling direct connection to a shared bus line. Its key electrical specifications include a typical propagation delay of 3.8 ns at 5V supply, a high output drive capability of ±12 mA at 5V that allows driving of capacitive loads and transmission lines, and a low 0.9V maximum input threshold at 3.3V VCC that ensures reliable operation with lower voltage logic signals. The device incorporates power-off high-impedance outputs that prevent backflow current when VCC is 0V, features Schmitt-trigger inputs with 500 mV typical hysteresis for improved noise immunity, and consumes an ultra-low 1 µA typical quiescent current that maximizes battery life in power-sensitive designs. It is widely deployed in smartphones, tablets, IoT sensors, portable medical devices and microcontroller-based systems that require reliable, single-channel signal buffering, level shifting and bus isolation with minimal board footprint and power consumption.
